[hylafax-users] limiting of hylafax port range usage

["Nenad Bulatovic" <nenad.bulatovic@xxxxxxxxx>]

I have one question, how to limit port range or to specify only one,
allways the same port for data transmission.
Somewhere I read that Hylafax uses RANDOM port for data transmission?

Accorrding to manual:
Communication between Cypheus and HylaFAX uses port 4559 except for
sending a TIFF file of an outbox fax. HylaFAX sends Cypheus a port
number (any high port 1024-65535) and Cypheus uses this port to send
the TIFF file. Therefore you need to open the firewall in order to
be able to use these ports in your internal LAN.
